My mother is 83 years old and has been living with Congestive Heart Failure for at least 5 years. Two years ago she was diagnosed with Pulmonary Hypertension. She also had a heart attack 15 years ago and has a pacemaker. I have noticed in the last 6 months that she is becoming very tired. She can not walk any distance and must take a nap in the afternoon. At times she is heard wheezing but it comes and goes. The doctor has her on oxygen at night. My question concerns travel. We are all going up to a wedding in the Washington D.C. area. I am a little concerned about this kind of trip for my mother. Could this make her condition worse? The wedding is of her granddaughter so it is a big family event. Any suggestions?
